Abstract
A horizontal dyestuff-supply tube within a cylindrical printing screen supports a prismatic applicator housing whose bottom is formed from two transversely spaced angle profiles for the guidance of a vertically movable distributing member. The latter is in the shape of a block with a multiplicity of vertical passages terminating at its underside in a discharge slot, the block penetrating upwardly into the applicator housing and supporting a perforated slack membrane of rubber or the like secured to the upper block surface and to the lateral inner bottom surfaces of the housing to form aprons preventing the penetration of dyestuff along the guide surfaces of the angle profiles. These profiles may be interconnected by transverse bolts passing through vertical clearances formed in the distributing member between its passages.
